Are you implying nobody human would work for Bing?

No, just that the chance of human involvement for two major search engines within an hour seems lower.

The .com site did completely disappear, and for a relatively high profile site like that, it's probably indexed pretty often.

There's also the possibility that the developers had access to the "Google Webmaster Tools" for cyanogenmod.com, even though they didn't own the domain, and so just told Google that the site had moved.
